Coast Guard crews are searching for a diver after he failed to surface
approximately 40 miles south of Nantucket this morning while diving on
the wreck of the Italian luxury liner Andrea Doria.

Coast Guard Sector Southeastern New England received a radio distress call
around noon from a 38-foot vessel reporting that one of their divers
had not surfaced at 11 a.m., as expected.

Two Jayhawk helicopter crews from Air Station Cape Cod, Mass., are searching the area and the Coast Guard Cutter Hammerhead, an 87-foot patrol boat from Woods Hole, Mass., is en route to the scene. The Hammerhead is expected to arrive around 5 p.m.

Coast Guard officials did not release the name of the dive boat.

"The
Coast Guard recommends taking all safety precautions necessary to
remain safe while diving and to always have a dive partner," said Petty
Officer 1st Class Stephen Kent, the search and rescue controller at
Sector Southeastern New England.

Here is an update I found from a Nantucket newspaper. This is very sad news indeed. My condolences go out to his family.

NEWS UPDATE: Andrea Doria diver's body identified

The body of a diver who failed to surface Wednesday morning after exploring the wreck of the Italian luxury liner Andrea Doria 50 miles south of the island has been identified as Terry DeWolf, 40, of East Hampton, N.Y. (A second newspaper reported him from Texas).

Coast Guard officials said Wolf's body was recovered by some of the nine other divers who dove on the wreck site with him earlier in the day.

The crew of the Coast Guard cutter Hammerhead assisted in recovering the body once it reached the surface. Wolf's body was transported by the dive boat he was on, the John Jack, to Montauk, N.Y., where it was positively identified by the East Hampton Police Department.

Diver dies exploring Andrea Doria wreck in Atlantic

A Houston man has become the 15th diver to die exploring the wreck of the ocean liner Andrea Doria since its sinking July 25, 1956, in the Atlantic Ocean south of Nantucket, Mass.

Terry DeWolf, 38, who was visiting the wreck on the New Jersey dive boat John Jack, temporarily based in Montauk Harbor, failed to surface as expected at 11 a.m. Wednesday, the Coast Guard and East Hampton police reported.

The Coast Guard is investigating the cause of death.

"He was overdue and found on the bottom near the wreck by crew members and other divers from the John Jack," said East Hampton Det. Sgt. Chris Anderson. "He had extensive dive certifications and was quite experienced."



Anderson said DeWolf died on his second dive of the trip. The 38-foot John Jack left Montauk on Monday and was scheduled to return today. Instead, it arrived at 8:30 a.m. yesterday to return the body.

John Jack owner Joseph Terzuoli of Wall, N.J., could not be reached for comment.

Typically, Northeast dive boats bring their customers to the site, where the divers are responsible for all aspects of the dive.

The Coast Guard received a distress call around noon from the John Jack and dispatched two Jayhawk helicopters and the cutter Hammerhead from Cape Cod, spokeswoman Connie Terrell said.

The deteriorating Italian liner, which lies on its side in 235 to 255 feet of water 40 miles south of Nantucket after colliding in fog with the Swedish liner Stockholm, is considered the Mount Everest for advanced shipwreck divers, who breathe a mixture of gases to cope with the depth while searching for china and other artifacts.

"The Andrea Doria is a particularly dangerous wreck because it's just so deep," said Kevin McMurray of upstate Brewster, author of "Deep Descent," a book about diving the Doria. "You hit the wreck at 190 feet, well below the safe diving recreational limit, which is 130 feet. You run into all kinds of problems: limited air supply, and you have to make a slow ascent to avoid decompression sickness.

"You often have problems because divers penetrate the wreck, and the decks are collapsing because it's been underwater for 52 years now. The wreck lies on its side, so the walls are now the floors and the floors are now the walls, and it's very confusing. It's a very dangerous labyrinth."
